Which frame included the WPA IE? Beacon? Probe Response? Have you
configured the AP to include SSID in the Beacon frames? If not, you will
need to add scan_ssid=1 to the network block in wpa_supplicant.conf.
Which version of wpa_supplicant and Host AP driver are you using? If you
cannot get this working, please send me a wireless sniffer log that
includes both the probe request from the client and matching probe
response and couple of beacon frames from the AP.
